TPM(Total Productive Maintenance) is a methodology to improve corporations' productivity and has been employed widely. At the initial stage of the TPM, we need to set basic plans and goals of the TPM. Also, quantization of performance is required through the TPM activity measurement indices to achieve the plans and the goals. We analyzed measurement factors of TPM activity by observation of previous researches and suggest a measure methodology of economic effect for the TPM performance measurement based on BSC and quantification of qualitative measurement.

Six Holstein heifer calves weaned at 45 days-of-age were randomly allocated into high daily gain (1.1 kg/d, HDG) and low daily gain (0.56 kg/d, LDG) groups, and were slaughtered at 170 kg of live weight. Energy intake level in the feeding period was 2.4 $\times$ maintenance in 105 days for HDG and 1.4 $\times$ maintenance in 216 days for LDG calves. Total length of the small intestine was identical between groups, but both weights of the pancreas and of the small intestinal mucosa were greater (p < 0.01) for HDG calves. Alpha-amylase, lipase, proteinase, and trypsin activities of the whole pancreas were higher (p < 0.05) in HDG calves. Disaccharidase activity of the whole small intestinal mucosa was also higher (p < 0.10) for HDG than for LDG calves. However, the enzymatic activities, expressed as per gram or per protein of the pancreas and the small intestinal mucosa, were not affected (p > 0.10) by the plane of nutrition. These results suggest that the digestive enzyme activity in the small intestine varies primarily with the weight of tissues synthesizing the enzyme.

Survival of thermotolerant Lactobacillus reuteri KUB-AC5 in $20\%$ (w/v) skim milk was found to be $11.3\%$ after spray drying by using a pilot scale spray dryer with inlet temperature at $170^{\circ}C$ and outlet temperature at $85^{\circ}C$. The ability of dried cell to produce antimicrobial activity was not affected by the spray drying. The model system for predicting viability of spray-dried L. reuteri KUB-AC5 during long-term storage was established, based on the Arrhenius equation, and verified by experimental data, because the viability of cells during storage can be correlated with storage temperature. The viability during storage at $30^{\circ}C$ declined more rapidly than that storage at $4^{\circ}C$.

This research is about the effect on children's brain before and after learning Baduk. The research was performed on 20 pupils attending I Baduk school with the contrast group of 20 pupils who did not take Baduk instruction. The pre-test on the brain waves before learning Baduk were measured from October 27, 2008 to November 7, 2008 and the post-test on the brainwaves after learning Baduk were measured from November 2, 2009 to November 4, 2009. The result confirmed the differences of both resistance activity quotient and emotion quotient. The result of the study suggest baduk study possibility in positively affecting the subjects' brain activation and emotion.

This study examined that how the corporate social responsibilities of a social enterprise affect their image and product attitude. In particular, separating into a real self-image and social self-image, the moderate effects of the accordance of self-image were tested. The results showed that each corporate social responsibility of a social enterprise affects their image except for social image. In addition, an accordance of the real self-image moderates the effect of the corporate activity image and social contribution activity image on the product attitude.

The goal of this research is to development a coordination supporting script in CSCL and tried to measure of coordination supporting script's effectiveness. Therefor, in this research, after derive macro-script design principle and activity principle from former study and CSCL tool, after derive micro-script from role sign several reference, and then based on those principle developed coordination supporting script. As providing coordination supporting script or not, there will be the sense making difference of effectiveness of coordination supporting script in learning activity(shared mental model). The result of this study may have implication for the research on macro-script and micro-script and educational practice.

The degradation of methylethylkeone(MEK) was investigated by the continuous single module photocatalytic reactor. Operational conditions were initial concentration of MEK, intensity of photon flux, and activity change according to the long time operation. The photocatalytic degradation was decreased with the increase of MEK concentration, and the degree of decrease was larger at higher flow rate. Removal efficiency of photocatalytic reactor was decreased with the increase of reactor diameter and lamp wavelength under the same residence time condition. Continuous single module photocatalytic reactor was successfully operated without any activity drop during 120hrs operation.

This work examined improving the activity of photocatalyts by novel metal doping for the degradation of volatile organic compounds, such as formaldehyde and acetone. The activity was determined with type of dopant novel metal and volatile organic compounds. The palladium-doped $TiO_2$ was found to be improved the decomposition of acetone. The photocatalytic degradation rate for acetone was increased with decreasing temperature to $45^{\circ}C$. The optmum temperature of photocatalytic degradation rate for formaldehyde was $75^{\circ}C$. The enhancement of reaction rate with novel metal were 1.0 wt.% of palladium for acetone, 1.0 wt.% of plaitnum for formaldehyde.

A comprehensive study to evaluate the relative antibrowning activity of 5 known natural juices was conducted. Among the juices tested, rhubarb juice showed the highest inhibitory activity on apple browning (${\Delta}L=0.47$ & ${\Delta}E=1.8$ after 6 storage days at $4^{\circ}C$). Even 50% diluted rhubarb juice was very effective in controlling apple discoloration, showing very limited change in Hunter's L and E values. No significant difference in apple slices browning was observed with respect to the packaging material (LDPE or nylon/PE). However, gas composition inside package was closely related to apple browning.

To introduce the antibacterial activity, ACF(activated carbon fiber) was impregnated by nano-sized Ag, Mn, and phosphoric acid. It was observed by the SEM analysis that Ag, Mn and phosphoric acid were properly impregnated at the ACF. The impregnated ACF showed lower adsorption performance than the pure ACF. It is found that ACFs impregnated by nano-sized Ag or phosphoric acid have a good antibacterial activity against bacillus cereus and salmonella entaritidis. but in the case of ACF impregnated with Mn, it have not any antibacterial effect on the bacillus cereus and salmonella entaritidis.
